You mean like Volt already does?!?!?!
Exactly. I'd hope an improved battery would avoid having to keep such a large buffer in reserve, but if not it could be a reasonable solution, as long as it does not drive the vehicle price higher.

While the volt does keep a larger reserve buffer, the 2013s are actually using a bit more of that reserve (at least as a percentage) because GMs experience and data suggests they can. Leaving unused battery will always impact the price, but better a slightly higher price and meeting/exceeding customer expectations than a lower price and unhappy customers. People getting >50miles per chage, which is my average since April, are very happy. People getting below EPA would be angry. I exceeded EPA even in the dead of CO winters.

Also remember the volt needs to be a bit more conservative as many drivers take it to minimum SOC every day, so they are getting a full swing every day which is more agressive in terms of the Depth-of-discharge, than many leaf drivers that don't go below LBW, and few get to VLBW. . As battery degradation tends to accelerate with DOD and age (weaker batteries have more internal resistance and use more DOD to get the same range, which degrades them faster, which needs more charge.. ) and because GM warranty covers capacity loss, they needed to be conservative. GM could have met their orginal goal of 40miles, but opening up that window, but it could just as easily have gone badly. Luckily for you, press on the Leaf battery issues is being way more forgiving than it was on say on the Volt battery non-issue.
Loving the Volt. I've saved 29 gallons compared to a BEV+CUV. From 10/29/11 to 12/29/12, went 11097 on 27.7 gallons of gas + 2742kWh Total fuel costs=$259.27, yielding: 0.25 gal./100mi, 400.5 MPG, 101.73MPGe, 166.5 MPG$ or $.0234/mi.

A higher priced LEAF that only meets the expectations that the original LEAF promised probably would not succeed. My thought and hope is that with two years of pack manufacturing under their belt and the new US plant they might be able to deliver a larger pack without raising the vehicle cost. In fact I'd say it's crucial that they do so.

This is my first post in the forum, so let me introduce myself. I’m Jeff Kuhlman, Head of Global Communications for Nissan Motor Co. I enter the forum a bit intimidated. I used to be quite involved in EV and advanced technology matters many years ago when I headed Communications for GM’s Energy and Environmental issues and Advanced Technology activities. Then I had the great fortune to work with some great people in the business, people who were my co-workers and my mentors – Bob Purcell, Denny Minano, Jon Beresa, Byron McCormick, Erhard Schubert, and Chelsea Sexton among the many.

If you know those names and their careers at GM, then you know that it was many years ago that I was involved with EVs. Since then I mostly have been involved with luxury brands, including Cadillac, Saab and Audi. Late last year, I joined Nissan in my current position. I work and reside in Yokohama, Japan.

As I read through your posts, it’s clear that we have much work to do on the communications front. And as I read your posts, I realize that you’re asking for more than that. What I can do is serve as one of the bridges to Nissan. Andy Palmer, Executive Vice President of Nissan, asked me to personally lead the global EV communications effort. That direction is clear, no delegation.

Fortunately, there is a good team that I get to work with, some you know, some you may not know. Many of you on the west coast have met or are familiar with Tim Gallagher, he’s on the team. Katherine Zachary is also on the team. She is located in Nashville, and if you haven’t met her, you’ve probably read her quotes. Dave Reuter, head of communications for the Americas (everything from Canada south through South America) is also on the team. We also have members from Europe, and we have two folks from Japan who are in Communications and are close to the battery team and the vehicle team.

I believe that my responsibility, and that of this team, is to promote, defend and engage. First, we have been too silent on what Nissan is working on, what we think the future looks like, and what innovations are coming. Second, we also have not defended Nissan or the LEAF as well as we could have when others – competitors, the anti-EV groups, and the media – lobbed verbal attacks at our company, our product and our motivations. Finally, we have not talked to you as frequently and as transparently as was needed.

On the last issue, there has been a debate in our profession about whether or not to participate in enthusiast forums, such as mynissanleaf.com. Too often such efforts, while noble, came off as spin. So, companies typically monitor the forums and then answer issues through their owned social platforms, such as YouTube, Facebook and Twitter. We have all of that, but we’re willing to talk here if invited. After reading through the responses to yesterday’s letter I realize that the discussions will often be tough, but that’s part of being the face of any company or brand. So, tell me when we’re falling short of the three areas that I’ve outlined above. My commitment to you is to monitor frequently, comment often and bring Nissan people – executives, engineers, designer, technologists – to this forum.

To start, on Thursday we will have a chance to sit down and talk with Andy Palmer while at the Paris Motor Show. Andy has agreed to take questions and to answer them in a video that we will post no later than Friday. We will begin to solicit questions via our Facebook page. I invite you to send your questions.

From now on I’ll keep my posts shorter, but I thought it important to let you know a little about me and what I’m going to be working on as it concerns the Nissan LEAF. Thanks for “listening”.

Welcome Jeff. I'm sure you'll receive a lot of questions and messages. By the way, Nissan were very involved on this board very early on. But over time backed away.

Chelsea, thank you for agreeing to lead Nissan's new EV technical advisory board! I feel this is a step in the right direction. Kudos to Nissan for taking this step.

I agree that Tony is an excellent choice for this board.

I recommend that you include at least one LEAF customer from Phoenix who has experienced both battery degradation and Nissan's response to date. In fact, I nominate Azdre for a position on your board! 8-)

You might also wish to include a LEAF customer on your board who also owns a Chevy Volt. Those customers can give you a more complete and impartial view of how each company communicates versus the other. There is a thread around here for owners of both cars if you wish to find out who they are.

I will also say there appears to be a rift between LEAF owners and Nissan dealership service departments as evidenced by a self-proclaimed Nissan service manager coming on here and complaining about LEAF customers. I think there may be several factors involved in this issue, but Nissan should keep an eye on it, IMO.

Finally, I will second Azdre's comment about the real issue being range and not kWh. It is extremely disingenuous for Nissan to proclaim that the battery capacity will be at 80% for the average LEAF after 5 years if internal electrical resistance simultaneously increases 400% (made up number) and range to automated nagging to plug in the car drops by 50%.

GREAT to see you hear, Jeff. WELCOME! I really look forward to future "conversations" and hope they will prove informative and helpful for all LEAF owners and the EV movement in general. Thank you for joining us on National Plug-In Day!

Trust me, Mr. Kuhlman, you are welcomed here with open arms. This kind of involvement is something I've been pleading to Messrs Reuter and Perry for much of last year. And I'm so, so glad to see it come to pass...I think it's a very positive step. Looking forward to a more open dialog with Nissan from here on in!

forgive if this is repetitive, as I didnt have time to read all 8 pages.

given what Nissan said in its letter and warranty material -- guaranteed loss of capacity over time -- would they please tell us what the replacement cost of the battery is?
some of us would want to keep the car because of its wonderful characteristics, but being limited to 80% of 75 miles in a daily commute -- largely freeway and some streets -- may mean we cannot use it in a couple of years for its primary purpose.

Added to the Wiki. Ockam, if you could check the mfg date on the body frame inside the driver's side door, we can add that to the data, and if you report this as a case to Nissan, please give us your Case # and the date you reported it. Thanks! :)
